Royal Purple XPR Racing OilMaterial Safety Data Sheet

Professional engine builders and race teams have cited increased horsepower and torque, and longer engine life with the use of Royal Purple. According to multi-year IHRA Top Fuel Champion Clay Millican, “When we Royal Purple XPR Racing oils are formulated for ultra-performance applications such as racing, modified engines and off-road usebegan using Royal Purple, I couldn’t believe the difference. Run any oil back to back with Royal Purple and you’ll see a difference.”

Independent tests on racing engines show as much as an 80% reduction in wear by using Royal Purple's XPR oils compared to other racing oils.

Royal Purple XPR Racing Oil combines the highest quality synthetic base oil, Royal Purple’s proprietary Synerlec additive technology and additional performance enhancers to create a lubricant that maximizes horsepower and torque, while providing the highest level of protection against heat and wear. Royal Purple XPR Racing Oil provides more protection than conventional motor oils - mineral or synthetic - including those combined with aftermarket additives.



XPR Extreme Performance and Racing oils:


XPR 0W10 is an ultra-light viscosity motor oil formulated for gasoline engines used in drag racing, motorcycle sprint racing, etc.


XPR 5W20 is a light viscosity motor oil formulated to withstand exotic fuels such as alcohol, methanol and nitrous oxide (NO2). Excellent for drag racing.


XPR 5W30 works well in a variety of applications from oval track late models to bracket racing. It is extremely versatile and produces excellent horsepower while preventing wear.


XPR 10W40 is designed for marine, oval track and endurance car racing. Capable of withstanding long intervals of extreme heat, it works especially well with alcohol and methanol. It is extremely popular in sprint cars, late models and World of Outlaws racing.


XPR 20W50 is formulated for running extended periods under extreme pressure and heat. It is used in oval track, marine and drag racing and is very popular in sprint cars, late models, truck pullers and bracket racing.

  • Extends Equipment Life
  • Compatible with Conventional Mineral and Synthetic Oils
  • Non-Foaming
  • Outstanding Rust / Corrosion Protection
  • High Temperature Service Capability

Royal Purple's lubricants can be used with exotic fuels. For the best protection, Royal Purple has formulated its XPR 5W20 and XPR 10W40 specifically with this in mind. These two oils are formulated to combat fuel emulsification to hold up even better than Royal Purple's other racing oils in alcohol and methanol applications.

Royal Purple has several options for racers. Its standard motor oils are formulated to outperform many of the "racing" oils on the market. But Royal Purple's XPR Extreme Performance & Racing oils redefine the category.

Royal Purple's XPR oils offer an even greater performance increase than its motor oils. With that said, the following are some guidelines to determine which products to use. As a point of reference, Royal Purple recommends using a racing oil that is closest in viscosity to the oil the race car is currently using (e.g. a racer using a conventional or synthetic 20W50 racing oil would be safe using either Royal Purple's SAE 20W50 motor oil or upgrading to Royal Purple's XPR 20W50). The tolerances to which the motor was built can play a role in an oil recommendation. Looser specs (e.g. greater than .003") might require heavier weight oil than a motor built to tighter specs (e.g. .002") to maintain idle oil pressure. Keep in mind that it is much easier to be conservative and use heavier weight viscosity oils and then go lighter when experience and comfort level dictate
